The app says a permission is off on my child's phone.

Open the child app on your child's phone. If a setting is off, the home screen shows a notice. Tap its button and follow the steps.

To turn them on in the phone's settings instead, check these items. Menu names vary a little by device.

• Location: Allow all the time and Use precise location
• Physical activity and Notifications
• Display over other apps, Usage access, and Accessibility
• Automatic date and time
